CA Syringe Filters, 1.2 um, 30mm, Luer-Lok/Luer Slip, Sterile, 100/Pk
Tisch SKU: SF18326

Tisch Scientific Cellulose Acetate (CA) Syringe Filters, 1.2 µm, 30 mm, 100/Pk - SF18326

Tisch Scientific carries a broad filtration catalog covering membranes, devices, and consumables for the laboratory. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The cellulose acetate membrane draws aqueous buffers through readily and handles water-based samples and low-alcohol solutions. The PP housing keeps the fluid path low in extractable contamination while resisting degradation from routine sample matrices and routes flow to minimize backpressure in service. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Naturally hydrophilic surface wets readily with aqueous samples
• Very low protein binding supports high recovery of dilute samples
• Stable with aqueous solutions, buffers, and alcohols across pH 4 to 8
• Smooth surface with low extractables and a uniform pore structure
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Rigid polypropylene body holds its shape under manual filtration pressure

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
